Overview of components
Fork material
The fork is made out of aluminum, which doesn’t add too much extra weight to the bike. However, it is not so stiff as steel or carbon forks are.
Wheels size
When leaving the production line, the LUMI 90 model has 20″ aluminum wheels. The 20″ wheels are a good fit for folding bikes, BMX, or children bikes. In conclusion, you can use them better on-road, and less on technical terrain.
Brakes
Stopping the bike when needed, it’s essential for your safety. This bike has Rim brakes. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they are not nearly as effective as hydraulic brakes are.
